4399-55-7 Usage
Description
Direct Blue 71 is an organic triazo dye and a water-soluble pollutant that is commonly found in industrial wastewater and can cause environmental pollution.
Uses
Used in Textile Industry:
Direct Blue 71 is used as a dye in the textile industry for coloring fabrics and garments.
Used in Wastewater Treatment:
Direct Blue 71 is used as a target pollutant in wastewater treatment processes, where various methods such as photocatalytic degradation using Au-Nx-TiO2 nanospheres are employed to decolorize and remove the dye from aqueous solutions, thereby reducing its environmental impact.
Used in Environmental Research:
Direct Blue 71 serves as a model compound in environmental research to study the effectiveness of various treatment methods in removing pollutants from water, as well as to understand the behavior and fate of dyes in the environment.
Preparation
3-Aminonaphthalene-1,5-disulfonic acid diazo, and Naphthalen-1-amine first coupling, its product to diazo, and 8-Aminonaphthalene-2-sulfonic acid second coupling, again diazo, in alkaline conditions and 7-Amino-4-hydroxynaphthalene-2-sulfonic acid third coupling.

Check Digit Verification of cas no
The CAS Registry Mumber 4399-55-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,9 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4399-55:
(6*4)+(5*3)+(4*9)+(3*9)+(2*5)+(1*5)=117
117 % 10 = 7
So 4399-55-7 is a valid CAS Registry Number.
